Eponine looked upwards again, hoping Violetta would join her, but her anticipation was not answered.  Eponine noted the slight damage her thrown hammers had done, which was somewhat expected.  She swatted away two incoming icicles with her hammer, and activated her shield to defend from the rest.  Eponine decided she needed to gain some height and started running along the ice columns interspersed within the sphere.  She moved with more confidence and recklessness, since a mistake would only drop her to the bottom of the ball, instead of plummeting into the sky eternally.  She also couldn't afford to be as slow as she was in the inverted trees or else the witch would be able to get some good hits on her, and Eponine was already feeling her soul gem darken from continued activation of her shield.  As she tried to reach higher ground, Eponine tried to be smarter about avoiding the witch's icicle attacks, by hiding behind columns and dodging rather than relying too heavily on her shield.

Once she was directly above the witch, she jumped down at it feet first, making her hammers longer and their heads bigger.  She held her arms out horizontally, and once she was about to hit the witch, swung her hammers downward so that each hammerhead would connect at the same time her feet struck the closest thing that could resemble the witch's head.  In this moment where her feet and the hammerheads impacted simultaneously, she activated her shield's rejection ability, multiplying the force of the impact. While her feet transferred force down vertically on the witch's head, the hammers, which swung in opposite arcs, dealt force horizontally, but on both sides of the witch's head, creating a three-way crushing force.  Eponine bent her knees, crouching on top of the witch and surveyed the damage.  If Byrea was about to retaliate, Eponine was already crouched and ready to leap off the witch at a moment's notice.  If the witch was stunned, but not yet defeated, Eponine would press the offensive.
